5 sociation with a window and sash construction.

The preferred embodiment of the invention constituting the subject matter of this application is a supplementary attachment and particularly designed to be built into a window sash,

whether it be of the double sliding type, or the casement window type.

Briefly stated, novelty is predicated upon a sash ventilator comprising a framed glass panel, means for rockably attaching the frame of the panel to an especially designed opening in the sash, together with foldable stay means for maintaining the ventilator in open and shut position, and collapsible end walls or shields arranged and constructed to augment the utility of the structure as a whole.

More specifically stated, I have evolved and produced a novel window and ventilator structure wherein the ventilator is of a retractable type, provided with collapsible end walls or shields and so constructed and mounted as to permit it to be folded neatly into the especially constructed portion of the window frame with which it is co-operable so as to provide a substantially weather-tight closure when the ventilator is not in use.

In the drawings:

Figure 1 is an elevational view of a window frame embodying upper and lower sliding sashes wherein the lower sash is revised to include the especially designed ventilator structure.

Figure 2 is a view showing the ventilator embodied in what may be designated as a casement window.

Figures 3 and 4 are vertical sections on the lines 33 and 4-4 respectively of Figure 2.

Figure 5 is an end view of the ventilator and its appurtenances viewed as a unit.

Figure 6 is an end view of Figure 5 showing the collapsible end walls folded.

Figure 7 is a detail sectional view of the lower end portion of the window sash showing the manner in which it is rabbeted and fashioned to accommodate the especially designed ventilator.

Figure 8 is an elevational view of a sheath.

Figure 9 is a cross section on the line 9-9 of Figure 8.

Figure 10 is a detail view of one of the leaves or shutters of the collapsible end wall construction.

Figure 11 is a section on' the line 11'1l of Figure 5.

Figure 12 is a top edge view of one of said end walls.

A general review of the different features of the drawings will disclose to the reader that the ventilator construction, considered as a unit, is the same, irrespective of the type of window in which it is embodied. In other words, the ventilator is the same in the easement window seen in Figure 3 as the sliding sash arrangement shown in Figure 1. For this reason, like reference characters are employed to designate like parts throughout the different views.

In Figure 1, the numeral 13 designates an ordinary frame, 14 represents the upper sliding sash, and 15 the lower sliding sash, The sash 15 is provided with the improved ventilator. It is believed however that the construction may be better illustrated by referring to Figure 3 in 'conjunction with Figure 2, wherein it will be observed that the casement window comprises a frame 16 having a swingably mounted sash pivoted in the frame as at 1'7 and including a suitable frame 18 and a glass panel 19. The ornamental beading of the frame 16 is fashioned as at 20 to accommodate the especially constructed lower end bar 21 of the swingable sash frame 18.

Co-operable with the frames 16 and 18 are triangular overlapping plates 22 and 23 of suit able proportions fastened together at their lower ends by pin and slot connections 24, these plates constituting a foldable closure or weathershield when the sash 18 is in outwardly swung position. The numerals 25 merely designate the pivotally mounted links of a stay device utilized for holding the sash propped out.

The lower end portions of the side bars of the stationary frame 16 are rabbeted as at 26 to provide abutments and the lower sill bar is cut out as indicated at 27 to form a receptacle for the adjacent or companion bar of the ventilator as well as to provide a fulcrum 27a on which the ventilator is slidable and rockable.

The ventilator per se is designated by the numeral 28 and comprises a frame 29 and a transparent glass panel 30. The lower bar of the ventilator frame, designated by the numeral 31 is fashioned and shaped to correspond with the similarly shaped lower end bar of the frame 16, as shown in Figure 3. It embodies a fulcrum lip 32 engageable with a similarly shaped lip and further embodies a shoulder 33 and an intervening inclined portion 34 shaped to slip down into the so-called receptacle in close fitting or matching relationship through the fulcrum bar 28.

The aforesaid collapsible end walls or shields are generally designated by the numerals 35 and each wall is made up of a plurality of shutter plates 36 having their lower curvate ends pivoted at 36a to the adjacent end bar of the ventilator frame as shown at Figure 5. These shutters are adapted to occupy either the expanded position seen in Figure 5 or the collapsed state represented in Figure 6.

The upper ends thereof are formed with horizontal slots 37 engageable with complemental pins 38 and these plates are disposed in overlapping relationship so as to facilitate expansion and collapsing. The numeral 39 designates an upper double link stay embodying pivoted links 40, while the numeral 41 represents the lower stay including short links 42. The links are pivotally connected to the ventilator and the window frame so as to hold the ventilator in outwardly swung operating position as seen in Figure 3, and to at the same time allow dropping and closing of said ventilator into the window frame when desired.

The numeral 43 merely designates one of a pair of channel shaped sheaths, each sheath being pivotally connected at 44 to the window frame and so located as to swing down over the upper edge portion of the shutters when the shutters are in extended position as shown in Figure 2.

The principal points of the construction to be borne in mind are these. The ventilator is usable with or without the collapsible end walls or shields. The ventilator per se preferably comprises the glass panel equipped frame of suitable proportions having its lower end bar fashioned to slidably and rockably engage the lower end bar of the window frame, whereby to permit said especially fashioned bar to come into close contacting or matching relationship when the ventilater is closed or to occupy the extended position represented in Figure 3 when the ventilator is in open position.

Upper and lower link stay devices are connected with the ventilator frame and window frame for the purposes specified. By preference however, the arrangement is especially designed to include the multiple shutter devices forming the end shields or end walls to provide effective closures between the ventilator and window frame when the ventilator is in extended position. The ventilator and its appurtenances may be utilized as an attachment susceptible of being applied to a conventional window structure by slightly altering the window frame or the entire window, sash and ventilator may be manufactured as a complete commodity ready for installation.

It is thought that the description taken in connection with the drawings will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

I claim:

1. In a structure of the class described, in combination, a window frame having its lower portion rabbeted to accommodate an especially constructed ventilator arrangement, the ventilator per se comprising a panel-equipped frame having its lower frame bar slidably and hingedly connected with the corresponding frame bar of the window frame, a pair of duplicate end closing walls for the ventilator, each end wall comprising overlapping shutters pivotally connected with the end bars of the ventilator frame, pin and slot connections connecting the upper end portions of said shutters with each other, pivoted link stay devices connected'with the window frame and ventilator frame for the purpose specified, together with a pair of duplicate channel shaped topping sheaths pivoted to the window frame and adapted to swing over the upper edges of the shutters when the shutters are extended into end Wall forming relationship.
